DESCRIPCIONDESCRIPTION

Liston de canto de material sintetico termoplastico, en particular para tableros para mueblesRidge edge of synthetic thermoplastic material, in particular for furniture boards

La invencion se refiere a un liston de canto de material sintetico termoplastico segun el preambulo de la reivindicacion 1, que puede fijarse sin pegamento con el lado trasero sobre tableros para muebles o similares.The invention relates to a edge strip of thermoplastic synthetic material according to the preamble of claim 1, which can be fixed without glue with the back side on furniture panels or the like.

Tales listones de canto se denominan tambien cantoneras, cintas de canto o listones de cobertura. En el caso de los tableros se trata preferiblemente de tableros de madera contrachapada, por ejemplo tableros de virutas o tableros de fibras (entre otros tableros MDF), que se utilizan para muebles.Such edge slats are also referred to as corners, edge tapes or cover strips. In the case of the boards, it is preferably plywood boards, for example chipboards or fibreboards (among other MDF boards), which are used for furniture.

Se conoce la utilizacion directa de pegamentos termofusibles en la denominada maquina encoladora de cantos para la fijacion de listones de canto a los lados estrechos de tableros para muebles. A este respecto, los pegamentos termofusibles se aplican sobre el liston de canto y/o sobre el tablero para muebles. Este procedimiento presenta la desventaja de que principalmente debido al pegamento termofusible se genera una junta visible entre el liston de canto y el tablero para muebles, que durante el uso del mueble es sensible a la suciedad y a la humedad. Dado que la aplicacion del pegamento termofusible tiene lugar mediante laminacion, aplicacion por rasqueta o por medio de aplicacion por boquillas, la aplicacion es irregular y encierra el peligro de adhesiones incorrectas. Ademas, este procedimiento requiere mucha energfa debido a la fusion del pegamento termofusible.The direct use of hot melt adhesives is known in the so-called edge gluing machine for the fixing of edge slats on the narrow sides of furniture panels. In this regard, the hot melt adhesives are applied on the edge slat and / or on the furniture panel. This method has the disadvantage that, mainly due to the hot-melt adhesive, a visible joint is generated between the edge slat and the furniture panel, which is sensitive to dirt and humidity during the use of the furniture. Since the application of the hotmelt glue takes place by means of lamination, application by doctor blade or by means of application by nozzles, the application is irregular and contains the danger of incorrect adhesions. In addition, this procedure requires a lot of energy due to the melting of the hot-melt glue.

En el documento DE 102006021171 A1 o el documento EP1852242 B1 se describe una cinta de canto denominada liston de cobertura, que esta prevista para su colocacion sobre una pieza de trabajo en forma de tablero y esta compuesta por un plastico termoplastico extruible.DE 102006021171 A1 or EP 1852242 B1 describes a edge tape called a cover strip, which is intended to be placed on a work piece in the form of a board and is composed of an extrudable thermoplastic plastic.

A este respecto, la capa de pegamento se aplica en forma de un pegamento termofusible mediante coextrusion sobre un liston de canto. La sujecion del liston de canto al tablero para muebles tiene lugar mediante la fusion o activacion de la capa de pegamento termofusible mediante radiacion laser directamente en el transcurso de la sujecion del liston de canto al tablero para muebles en la maquina encoladora de cantos.In this regard, the glue layer is applied in the form of a hot-melt glue by co-extrusion on a edge strip. The fastening of the edge slat to the furniture panel takes place by means of the fusion or activation of the hot melt adhesive layer by means of laser radiation directly in the course of the fastening of the edge slat to the furniture panel in the edge gluing machine.

Por el documento EP 1163864 B1 se conoce una union sin pegamento entre un liston de canto, que esta compuesto por capas de plastico de diferente dureza, y un tablero para muebles. La superficie del canto de plastico se funde mediante radiacion laser en la maquina encoladora de cantos, de modo que tiene lugar una union por soldadura laser del liston de canto con el tablero para muebles.From EP 1163864 B1, a bond is known without glue between a edge slat, which is composed of layers of plastic of different hardness, and a furniture panel. The surface of the plastic edge is melted by laser radiation on the edge gluing machine, so that a laser welding connection of the edge strip with the furniture panel takes place.

El documento DE 202007011911 U1 describe igualmente un liston de canto termoplastico, que presenta una capa de fusion coextruida, que puede fundirse por medio de radiacion laser y por consiguiente unirse a tableros para muebles. La capa de fusion presenta para ello una base qrnmica diferente y un menor punto de fusion que la capa estructural o lado superior del liston de canto.DE 202007011911 U1 also describes a strip of thermoplastic edge, which has a coextruded melting layer, which can be melted by means of laser radiation and consequently joined to furniture panels. For this purpose, the melting layer has a different chemical base and a lower melting point than the structural layer or upper side of the edge strip.

Todos los procedimientos mencionados anteriormente presentan en la practica la grave desventaja de que tales listones de canto tanto con capas de pegamento termofusible como con capas de fusion tras la sujecion del liston de canto a un tablero para muebles, durante el mecanizado con arranque de virutas posterior del liston de canto mediante, por ejemplo, fresado, conlleva un comportamiento de desprendimiento de virutas no homogeneo condicionado por las diferentes durezas o diferentes puntos de fusion y/o debido a polfmeros de base que difieren enormemente en las capas del liston de canto. De este modo se generan diferentes estructuras superficiales de las capas, que son visibles y pueden evaluarse visualmente como negativas. Esta desventaja es importante en particular en las uniones de esquina de los listones de canto a un tablero para muebles asf como en el caso de sobrelacados posteriores del tablero para muebles canteados.All the aforementioned processes present in practice the serious disadvantage that such edge slats, both with layers of hot melt adhesive and with melt layers after the edge slat attachment to a furniture panel, during subsequent chip cutting machining. of the edge strip by, for example, milling, involves a non-homogenous shaving behavior conditioned by the different hardnesses or different melting points and / or due to base polymers that differ greatly in the layers of the edge strip. In this way, different surface structures of the layers are generated, which are visible and can be evaluated visually as negative. This disadvantage is particularly important in the corner joints of the edge slats to a furniture panel as well as in the case of rear overlays of the board for edged furniture.

Por tanto, la invencion se basa en el objetivo de crear un liston de canto a partir sintetico termoplastico en particular para tableros para muebles, que se caracteriza por un comportamiento de desprendimiento de virutas homogeneo de todo el liston de canto y que puede sujetarse sin pegamento y sin una junta reconocible opticamente a un tablero para muebles.Therefore, the invention is based on the objective of creating a synthetic edge strip of thermoplastic synthetic in particular for furniture panels, which is characterized by a homogeneous shaving behavior of the entire edge slat and can be fastened without glue and without an optically recognizable board to a furniture board.

El objetivo de la invencion se alcanzo mediante un liston de canto con la combinacion de caractensticas segun la reivindicacion 1, comprendiendo las reivindicaciones dependientes configuraciones y perfeccionamientos convenientes.The object of the invention was achieved by a singing slat with the combination of features according to claim 1, the dependent claims comprising suitable configurations and improvements.

Por tanto, la invencion proporciona un liston de canto, que como liston de canto sin pegamento de multiples capas dispone de una capa de fusion que fluye de manera extremadamente facil en estado fundido, que presenta una dureza y una temperatura de fusion comparables con las de otras capas, de modo que todo el liston de canto presenta una dureza y una temperatura de fusion constantes, estando compuesto el liston de canto por una capa superior de polfmeros, concretamente homopropileno asf como una capa de fusion coextruida, que se basa en un polfmero que fluye facilmente de la misma base qrnmica, concretamente homopropileno con un mdice de fluidez (MFI) por encima de 25 g/10 min, preferiblemente por encima de 50 g/10 min (segun la norma ISO 1133, 230°C, 2,16 kg). Esta capa puede fundirse mediante aporte de energfa, por ejemplo mediante radiacion laser o plasma, de modo que el liston de canto puede sujetarse a tableros para muebles sin adicion de pegamento. La capa de fusion esta tenida en una configuracion de la invencion.Therefore, the invention provides a edge slat, which as a multi-layered glueless edge strip has a melt layer that flows extremely easily in the molten state, having a melting hardness and melting temperature comparable to those of other layers, so that the entire edge strip has a constant hardness and melting temperature, the edge strip being composed of an upper layer of polymers, namely homopropylene as well as a coextruded melting layer, which is based on a polymer which flows easily from the same chemical base, namely homopropylene with a flow index (MFI) above 25 g / 10 min, preferably above 50 g / 10 min (according to ISO 1133, 230 ° C, 2, 16 kg). This layer can be melted by supplying energy, for example by laser or plasma radiation, so that the edge strip can be attached to furniture boards without the addition of glue. The fusion layer is held in a configuration of the invention.

El liston de canto esta compuesto en un ejemplo de realizacion de homopropileno tenido.The edge strip is composed in an example of a homopropylene embodiment.

El grosor del liston de canto se encuentra preferiblemente en el intervalo de desde esencialmente 0,3 hasta 4 mm. El lado superior visible del liston de canto tenido puede estar grabado y/o impreso y/o barnizado y/o estar laminado con una lamina de plastico o de metal.The thickness of the edge strip is preferably in the range of from essentially 0.3 to 4 mm. The visible upper side of the edge strip may be engraved and / or printed and / or varnished and / or laminated with a sheet of plastic or metal.

Ademas son posibles los denominados efectos de veteado en las capas. Los efectos de veteado se generan tal y como se conoce mediante coextrusion del mismo polfmero en un ajuste de otro color o mediante una distribucion de colorante no homogenea. La distribucion en bandas, de otro color, optimiza la reproduccion optica de adornos de madera.In addition, the so-called streaking effects in the layers are possible. The streaking effects are generated as known by co-extrusion of the same polymer in a different color setting or by a non-homogeneous color distribution. The distribution in bands, of another color, optimizes the optical reproduction of wooden ornaments.

Una realizacion preferida adicional de la invencion se refiere a un liston de canto de dos o mas capas, que se fabrica mediante coextrusion. La coextrusion de la capa de fusion puede tener lugar tanto en un procedimiento directamente con la extrusion de las otras capas y/o mediante una postcoextrusion posterior.A further preferred embodiment of the invention relates to a edge strip of two or more layers, which is manufactured by co-extrusion. The co-extrusion of the fusion layer can take place either in a process directly with the extrusion of the other layers and / or by a subsequent post-extrusion.

Tambien resulto ser ventajosa una laminacion de la capa de fusion en un procedimiento de dos etapas. En la primera etapa de fabricacion se extruye la capa de fusion como lamina. A continuacion tiene lugar la laminacion de esta lamina sobre el lado trasero del liston de canto. La interconexion firme de las capas durante esta laminacion se genera mediante temperatura y presion en un alisador.A lamination of the melt layer in a two-stage process also proved advantageous. In the first manufacturing step, the melt layer is extruded as a sheet. The rolling of this sheet on the back side of the edge slat then takes place. The firm interconnection of the layers during this lamination is generated by temperature and pressure in a smoother.

Ademas, la capa de fusion puede generarse mediante un recubrimiento lfquido, que se vuelve solido mediante reticulacion o secado. Una realizacion de dos o mas capas de este tipo presenta la ventaja de que la capa de fusion, las capas intermedias y la capa superior pueden formularse por separado segun sus funciones. Las capas intermedias pueden actuar como agentes adhesivos entre polfmeros incompatibles, que no pueden combinarse mediante coextrusion.In addition, the fusion layer can be generated by a liquid coating, which becomes solid by cross-linking or drying. An embodiment of two or more layers of this type has the advantage that the melting layer, the intermediate layers and the upper layer can be formulated separately according to their functions. The intermediate layers can act as adhesive agents between incompatible polymers, which can not be combined by coextrusion.

La invencion propone preferiblemente un liston de canto de dos capas, compuesto por una capa superior de los polfmeros mencionados anteriormente, en particular homopropileno, asf como una capa de fusion coextruida, que se basa en un polfmero que fluye facilmente de la misma base qmmica, en particular homopropileno, con un mdice de fluidez (MFI) por encima de 25 g/10 min, preferiblemente por encima de 50 g/10 min (segun la norma ISO 1133, 230°C, 2,16 kg).The invention preferably proposes a two-layer edge slat, consisting of a top layer of the aforementioned polymers, in particular homopropylene, as well as a co-extruded melting layer, which is based on a polymer that flows easily from the same chemical base, in particular homopropylene, with a melt index (MFI) above 25 g / 10 min, preferably above 50 g / 10 min (according to ISO 1133, 230 ° C, 2.16 kg).

Mediante el uso de la misma base polimerica en la capa superior y en la capa de fusion, el comportamiento de desprendimiento de virutas, la dureza y la temperatura de ablandamiento de todo el liston de canto son muy homogeneos, de modo que visualmente no puede reconocerse ninguna diferencia en el color, el brillo y/o la estructura como resultado del mecanizado con arranque de virutas del liston de canto tras la sujecion al tablero para muebles.By using the same polymer base in the upper layer and in the melting layer, the shaving behavior, the hardness and the softening temperature of the whole edge slat are very homogeneous, so that visually it can not be recognized no difference in color, gloss and / or structure as a result of chip cutting machining of the edge slat after fastening to the furniture board.

El uso de polfmeros que fluyen facilmente para la capa de fusion presenta la ventaja de que el polfmero de la capa de fusion en estado fundido fluye a la estructura de poros abiertos del tablero para muebles y puede anclarse bien mecanicamente en el mismo. Por consiguiente, se consigue calidades de pegado altas.The use of readily flowing polymers for the melt layer has the advantage that the polymer melt layer flows into the open pore structure of the furniture board and can be mechanically anchored therein well. Consequently, high bonding qualities are achieved.

Ademas, se genera una junta cerrada entre el liston de canto y el tablero para muebles, de modo que se consigue una alta resistencia frente a la humedad y con ello frente a hinchamientos del tablero para muebles mediante la absorcion de agua asf como la adherencia de suciedad.In addition, a closed joint is generated between the edge slat and the furniture panel, so that a high resistance to humidity and thus against swelling of the furniture panel is achieved by the absorption of water as well as the adhesion of the furniture. dirt.

Para una absorcion optima de la radiacion laser y la transformacion de la radiacion laser en energfa termica o la absorcion de la energfa del plasma pueden utilizarse aditivos que absorben energfa, preferiblemente aditivos que absorben luz y/o radiacion asf como calor, por ejemplo pigmentos laser, cargas minerales o partfculas de metal. Esto tiene la ventaja de que la absorcion de energfa y con ello el comportamiento de fusion de la capa de fusion puede adaptarse de manera dirigida a la fuente de energfa, por ejemplo la longitud de onda de la radiacion laser.For optimal absorption of laser radiation and the transformation of laser radiation into thermal energy or the absorption of plasma energy can be used additives that absorb energy, preferably additives that absorb light and / or radiation as well as heat, for example laser pigments , mineral charges or metal particles. This has the advantage that the absorption of energy and thus the melting behavior of the fusion layer can be adapted in a targeted manner to the energy source, for example the wavelength of the laser radiation.

Una realizacion adicional se refiere a un liston de canto segun una de las realizaciones mencionadas anteriormente, aplicandose sobre la capa de fusion del liston de canto un recubrimiento lfquido, que contiene aditivos que absorben energfa y se seca o reticula termica y/o qmmicamente. El recubrimiento lfquido puede tener lugar para ello tanto por toda la superficie como solo en superficies parciales o zonas de la capa de fusion. Con ello pueden fundirse de manera dirigida zonas definidas espacialmente de la capa de fusion con la fuente de energfa durante el procesamiento, de modo que la interconexion entre el liston de canto y el tablero para muebles puede definirse igualmente en una posicion exacta.A further embodiment refers to a edge slat according to one of the aforementioned embodiments, a liquid coating, containing additives that absorb energy and thermally and / or chemically dried or crosslinked, is applied over the melt layer of the edge slat. The liquid coating can take place both on the entire surface and only on partial surfaces or areas of the melting layer. As a result, spatially defined regions of the melting layer can be locally fused with the energy source during processing, so that the interconnection between the edge strip and the furniture panel can also be defined in an exact position.

Para una mejor union de los aditivos y en particular de cargas minerales a la base polimerica y para un aumento simultaneo de las fuerzas de adhesion del liston de canto a materiales derivados de la madera, la capa de fusion puede mezclarse tal y como se conoce con aditivos con grupos funcionales, tal como por ejemplo anhudrido del acido maleico o a base de isocianato.For a better union of the additives and in particular of mineral charges to the polymeric base and for a simultaneous increase of the adhesion forces of the edge slat to wood-derived materials, the fusion layer can be mixed as it is known with additives with functional groups, such as, for example, maleic acid anhydride or isocyanate-based anhydride.

Una realizacion preferida adicional de la invencion se refiere a un liston de canto segun una de las realizaciones mencionadas anteriormente, presentando la capa de fusion y/o las capas intermedias una estructura de espuma. La estructura de espuma puede generarse mediante la espumacion tanto ffsica como qmmica de la capa polimerica. SeA further preferred embodiment of the invention relates to a edge slat according to one of the aforementioned embodiments, the melt layer and / or the intermediate layers having a foam structure. The foam structure can be generated by both physical and chemical foaming of the polymeric layer. He

muestra que se aumenta la absorcion de ene^a de la capa de fusion (por ejemplo tras radiacion laser). De este modo puede reducirse el rendimiento de ene^a (por ejemplo del laser) con una misma calidad de adhesion y/o aumentarse la velocidad de avance del proceso de union y/o reducirse la concentracion de los aditivos que absorben energfa. Todas las medidas mencionadas anteriores conducen a una reduccion de los costes.shows that the uptake of energy from the fusion layer is increased (for example after laser radiation). In this way, the performance of ene (for example of the laser) can be reduced with the same quality of adhesion and / or the speed of advancement of the joining process can be increased and / or the concentration of the energy-absorbing additives can be reduced. All the measures mentioned above lead to a reduction in costs.
